--------------------------------
Summary: Update capped to 1Hz when in background
Key: CB-11291
URL: https://issues.apache.org/jira/browse/CB-11291
Project: Apache Cordova
Issue Type: Bug
Components: Android, Plugin Device Motion
Reporter: Zeph Davies
Due to the way Android's WebBrowser handles setInterval, when the "tab" is in
the background (ie when used in conjunction with backgroundMode plugin),
setInterval (used to send the latest value to the application) is capped to 1Hz
(once per second).
This makes the plugin update at a completely different interval to that set by
the application.
One solution is to use a WebWorker to hold the setInterval timer, as it is not
limited by the browser.
The tricky bit is loading the script into the WebWorker, as it requires the
"Content-Security-Policy" to allow local files or blobs.
